A version of the other gist closure.js but with a simpler syntax for beginners
function makeCounter(initialValue) {
let count = initialValue;
function toString() {
return 'The count is ' + count +'.';
}
return {
add: function() { return ++count },
sub: function() { return --count },
val: function() { return count },
toString: toString
